Kinematic and kinetic gait principal component domains in older adults with and...
Moreira, Juliana; Cunha, Bruno; Félix, José; Santos, Rubim; Sousa, Andreia S. P.Objectives: Gait kinematic and kinetic changes have been identified in older adults, highlighting the need to explore the principal age-related components and how these are associated with functional disability. This study aims to perform a factor analysis, including gait kinematic and kinetic parameters in older adults to establish determinant gait domains. Additionally, this study aims to identify which domai...
The influence of artificial breast volume induction on postural stability, post...
Guedes, Diana C.; Carneiro, Daniela F.; Alves, Leonel A. T.; Melo, Ana S. C.; Moreira, Juliana; Cunha, Bruno; Santos, Rubim; Noites, Andreia(1) Background: The percentage of breast augmentations has increased in recent years alongside the frequency of implant removals. Musculoskeletal and postural disorders are often overlooked during this removal process. Research indicates that excess anterior load from breast implants can disrupt postural control and potentially lead to short- or long-term musculoskeletal dysfunction. This study aims to evaluate...

Beyond low back pain! The influence of physical activity on mental health, refl...
Parolini, Franciele; Becker, Klaus; Goethel, Márcio; Fernandes, Ricardo J.; Fonseca, Hélder; Ervilha, Ulysses F.; Vilas-Boas, João Paulo; Santos, RubimPsychological factors play a crucial role in the experience of acute low back pain and may influence functional outcomes. However, the interplay between these factors and levels of physical activity remains poorly understood. This cross-sectional observational study examined the relationship between psychological variables and functional disability in individuals with acute low back pain, considering different ...
Precision and reliability of a dynamometer for trunk extension strength and ste...
Parolini, Franciele; Goethel, Márcio; Robalino, Johan; Becker, Klaus; Sousa, Manoela; Pulcineli, Barbara C.; Ervilha, Ulysses F.; Vilas-Boas, João PauloLow back pain is a major cause of disability worldwide, often associated with deficits in trunk extensor strength control. Accurate assessment of trunk extension strength control is crucial for diagnosing impairments and monitoring interventions. This study evaluated the reliability of a dynamometry-based protocol for isometric trunk extension strength control assessment. Twenty-eight healthy volunteers (9 fema...
Sit-to-stand and stand-to-sit kinematics in older adults with and without funct...
Moreira, Juliana; Cunha, Bruno; Félix, José; Santos, Rubim; Sousa, Andreia S. P.Objective Sit-to-Stand (Sit-TS) and Stand-to-Sit (Stand-TS) transitions are essential daily movements affected by ageing and disability. This study aimed to explore related kinematic domains in older adults with and without disability. Methods A cross-sectional study including adults aged 60 years or older, with (n = 25) and without disability (n = 35). Comparisons between groups included task time, centre of m...
Kinematic Biomarkers of Functional Disability in Older Adults: Analysis of the ...
Moreira, Juliana; Cunha, Bruno; Félix, José; Santos, Rubim; Sousa, Andreia S. P.The Timed Up and Go (TUG) test is used to assess mobility in older adults, but its reliance on completion time limits its insight into detailed movement patterns that could serve as early indicators of functional decline. This study aimed to identify lower limb and trunk kinematic biomarkers during the TUG test that distinguish between older adults with and without functional disability, emphasizing the potenti...
Disrupted corticomuscular coherence and force steadiness during acute low back ...
Parolini, Franciele; Becker, Klaus; Ervilha, Ulysses F.; Santos, Rubim; Vilas-Boas, João Paulo; Goethel, Márcio Fagundes; Rubim Silva Santos, ManuelAcute low back pain can impair motor control, yet its effects on force steadiness and cortical activity remain unclear. Thirty-three healthy adults (25 men, 8 women) performed a sustained spinal extension task at 20% of their maximum voluntary contraction under pre- and during-pain conditions induced by a hypertonic saline injection, as well as pre- and post-isotonic injection. Electromyography was recorded fro...
Principal component analysis of stair negotiation and floor transition kinemati...
Moreira, Juliana; Teles, Ivone da Silva; Cunha, Bruno; Félix, José; Guedes, Diana C.; Alves, Leonel A. T.; Santos, Rubim; Sousa, Andreia S PStair negotiation (ascending and descending) and transitions to level walking are complex motor tasks influenced by aging; yet the impact of functional disability on these changes remains underexplored. This study aimed to evaluate the lower limb joint positions, velocities, and the center of mass (CoM) displacement and velocity during stair negotiation and transitions in older adults with and without functiona...
